Key product information and technical features.
The PXI-7811 combines digital I/O with onboard FPGA logic rather than a fixed-function analog acquisition architecture. Its 160 bidirectional lines and Virtex-II XC2V1000 FPGA provide the hardware foundation for user-defined digital behavior.
NI identifies this module within its R Series ecosystem, whose onboard FPGA is programmed using the LabVIEW FPGA Module. NI also provides model-specific cable and connector-block guidance for wiring the digital interfaces.

Product-specific answers based on available technical information.
It provides 160 bidirectional digital I/O lines and a Virtex-II XC2V1000 FPGA.
NI lists the SHC68-68-RDIO cable with SCB-68 or SCB-68A connector blocks for the PXI-7811. Follow the model-specific pinout when wiring either block.
Both provide 160 digital I/O lines. The PXI-7811 uses a Virtex-II XC2V1000 FPGA, while the PXI-7813 uses a Virtex-II XC2V3000 FPGA.
